Simulation-based Method for Computation Reliability and Optimum Quantity of N:K(m) Cross-Strapping Standby System

：In this paper, a queue network based simulation model is applied to describing the (m) cross-strapping standby system. Algorithms for computation reliability and optimum quantity of (m) system are provided. Our approach is applicable to complex non-Markovian model of (m) system with multi-repairer. Finally, the reliability and optimum quantity of Markovian (m) system are calculated with both analytical method and our method, the two results fit well. Our research may be used as the basis for further study of the (m) system.
